dnsmasq: add support for set: and tag: pairs
On my network, I have a variety of machines and appliances, some of which need different configuration issues than the default options.
For example:
config host
option name 'client'
option mac '00:01:02:03:04:05'
option ip '192.168.1.20'
option tag 'acme'
config tag acme
option force '1'
list dhcp_option 'option:router,192.168.1.253'
list dhcp_option 'option:domain-name,acme.com'
list dhcp_option 'option:domain-search,acme.com,redfish-solutions.com'
which allows me to override the default router for my client's host, as well as its domain-name, and its domain-search.
this causes the following config lines:
dhcp-host=00:01:02:03:04:05,set:acme,192.168.1.20,client
dhcp-option-force=tag:acme,option:router,192.168.1.253
dhcp-option-force=tag:acme,option:domain-name,acme.com
dhcp-option-force=tag:acme,option:domain-search:acme.com,redfish-solutions.com
This could be useful elsewhere, for instance, if you have an IP CCTV that you don't want to have a default-route, etc.
